l Rail-Joints; and I do hereby declare that the following is a full, clear, and exact descrip-v tion thereof, reference being had tothe accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciiication.

' This invention relates to improvements in rail-joints of that class in which the joint embraces a base-plate which supports the meeting @nds of the rails, two joint-bars,` and a longitudinal stiifening plate or girder.

The invention consists in the matters hereinafter described, and pointed out in the appended claims. i

As shown in the accompanying drawings, Figure l is a plan view of a rail-joint embodying one form of my invention. Fig. 2 is a si e elevation of the same. Fig. 3 is a transverse section taken upon line 3 3 of Fig. 2. Fig. 4 is a transverse section showing a construction generally similar to that shown in Figs. 1, 2, and 3, but which embraces two stiiiening plates or girders, one located at each side ofthe base-plate. Fig. 5 shows another form of joint which is generally like that shown'in Fig. 4,.but in which the stiiening plates or girders are provided with oblique inner faces. Fig. 6 is a modification of the construction shown in Fig. 5, in which each stiffening plate or girder is provided with two oblique faces' adapted to act upon corresponding oblique faces formed upon the .joint-bars. Fig. 7 is a view in cross-section of a joint like that'shown in Fig. 6, but having one girderplate and one flanged joint-bar only.'

As shown in the said drawings, A A indicates the meeting ends ofthe rails; B, a horizontal base-plate, on which said meeting ends of the rails rest, and C O two joint-bars, which are fitted between the under faces of the rail-heads and the top surfaces of the base-flanges of the rails.

As shown in Figs. 1, 2, and 3, D indicates a longitudinal vertically-arranged stifening or girder plate located at the outer side of the joint and having interlocldng engagement at its lower margin with the adjacent side margin of the base-plate B in such a manner that said girder-plate is laterally movable or adjustable with respect to the base-plate, but, is held from vertical movement relatively to said base plate throughout its length, so that it serves as a stifening member for the base-plate, acting to prevent or restrain bending or iieXure of said b aseplate under vertical or downward strains. E E designate track-bolts, which are inserted through the rails, j oint-bars, and the girderplate for clamping said parts together. At its side margin adjacent to the girder-plate D the base-plate is provided on its u per surface at one side of the rail-seat wit an inwardly -facing longitudinal shoulder b, against which laterally bear the adjacent side margins of the base-flanges of the rails. The said-shoulder I) is designed to take the lateral stress on the rails due to the pressure on the inner edges of the rail-heads of the wheel-flanges, and the base-plate is therefore arranged with its shoulder l) at the outer side of the rail. The base-plate is provided near its inner margin with spike-'holes b' b-,"

through which are inserted spikes, as shown at F in Figs. lZfand 3, for the holding of the base-plate to the'tie and preventing outward shifting or movement of the base-plate on the tie. To provide `for the interlocln'ng connection of the outer margin of the base-plate with the girder-plate D, a construction provided, as follows: On the outer margin of the base-plate is formed a longitudinal outwardly-extending horizontal flange B", located above the level of the bottom surface of the base-plate. The lower part of the girder-plate D is shaped toisurround or em brace the flange B', and for this purpose is extended outwardly over the top ofl said ilange and has at its lower margin an in wardly-extending iiange d, which projects beneath the flange B of the base-plate, said flange d with the part of the girder-plate above it forming a groove D', having horizontal top and bottom surfaces and ada ted to receive said flange B on the base-p ate. Said girder-plate is shown as having a'bottom horizontal bearing-surface, which is ush with the horizontal bottom surface of the base-plate and is thereby adapted to rest on the tie. 'The girder-plate is shown as also provided at its lower margin with an u .v e which forms with the flange'd a flat horizon bearing-surface on the girder-plate located 1n the same horizontal plane with the bottom 5 surface of the base-plate B and adapted for contact with the tie. The outwardly-extending flange D2 is preferably rovided with apertures d d', through which spikes, one of which is shown at F in Fig. 3, may be driven to hold the girder-plate in contact with the tie. The said apertures d d are transversely elongated or have the form of open notches, as shown in the drawings, in order to permit the girder-plate to be shifted toward the baseplate in tightening the joint, as hereinafter described. j In the form of joint shown in said Figs. 1, 2, and 3, the joint-bar C', adjacent to the said girderplate D, is provided with upper and lower outwardly-extending longitudinal flanges c c, the upper flange being located above the track-bolts E E and the lower flange being in contact with the base-flange of the rail, said flanges c and c being adapted for contact at their outer edges with lthe inner face of the 'girderlate, so that when the base-flange of the rail) is in bearing against the shoulder b of the base-plate the main part of the girder plate will rest or bear against the said flanges c'c of the joint-bar C. It will be understood that the baseplate is permanently secured in position uponthe ties and that any outward movement of the rails fromthe normal position thereof is prevented by contact of the outer margins of the base-flanges of said rails with the shoulder b; The flanges-c and c on the joint-plate C serve not only to transmit the inward pressure of the girderplateto the body of the said joint-plate, thereby forcing the sameA into contact with the rails when the track-bolts ,are tightened, but said flanges also serve-to give longitudinal stiffness to the said joint-bar, giving it greater capacity to resist tendency to bending or fleXure `under both vertical and horizontal strains or stresses. In assembling the parts of the joint the base-plate is secured in proper position upon the ties with its shoulder b in bearing against the outer margin of.

the base-flange of the rails, and when it becomes necessary to tighten the joint .by screwing up the nuts on the track-bolts E such tightening may be accomplished without shifting in position of the rails on the base-plate, because under any shifting of the joint-bars C and C in the tightening of the joint said girder plate will be shifted slightly inward. This movement of the girder-plate is permitted by the horizontallysliding interlocking connection of the girderplate and base-plate afforded bythe flange b and the groove D without affecting the interlocking engagement or connection of the girder-plate with the lbase-plate, by which the base-plate is stidened or held from vertical fleXur'e to such-1 an extent as is afforded by the stiffness or-capacitygto resist vertical fiexure of the girder-plate itself.

In the construction illustrated in Fig. 4 a

base-plate G is provided generally like that of the base-plate B before described inconnection with'Figs.v l, 2, and 3, but which is providedA with two inwardly-facing shoulders g g at both the inner and outer sides of the rail-seat and having at its outer and inner edges horizontal outwardly-extending flanges G G2. At opposite sides of the rails are located j oint-bars H II. In this construction two stiffening plates or girders I and J are employed, the same corresponding generally in construction with the girder-plates E. (Shown in said Figs. 1, 2,and3.) The girderplate I has a horizontal flange i extending beneath the flange G of the base-plate and forming a groove I to receive said flange G', together with an outwardly-extending horizontal flange I2, adapted to rest upon the tie, while the girder-plate J is likewise provided with an inwardly-exteiiding horizontal flange j', extending beneath the flange G2 and forming with the part of the girder-plate above it a horizontal groove J and with an outwardly extending flange J2. In this instance trackbolts, one of which is indicated by K, are in'- serted through the two girder-plates I and J and through the j oint-bars H and H and the ends of the rails, while the flanges I2 J of the girder-plates are provided with notches to receive the spikes L L. The girder-plates J,

^ which are located at the inner sides of thel rails, are made lower than the girder-plates I at the outer sides thereof, in order to afford rooin or space for the wheel-flanges. In the construction shown in said Fig. 4 I provide stiffening-girders for both the inner and outer sides of the joint, thus greatlyincreasing the stiffness of the saine and providing a great degree of rigidity to resist vertical strains, while at the saine time by reason of the interlocking connection of both of the girder-plates with the side margins of the base-plate provision is made for tightening the joint without affecting the alinement of the rails or gage ofl the track, it being of course understood that in tightening the joint both of the girder-plates will be shifted inwardly toward the rails, while the baseplate will remain in its normal position or will not be shifted.

In Fig. 5 I have shown still another fornr IOO ICS

girder-plates T and U are provided at their sure of the joint-bars against the base-flanges of the rails when the said girder-plates are drawn inwardly by the track-bolts in tightening the joint. When the track-bolts are tightened, therefore, the girder-plates will be lifted and the base-plate connected therewith thereby clamped firmly against the base-flanges of the rails. This construction has the manifest advantage that in screwing up the nuts on the track-bolts the parts constituting the joint will be tightened or drawn together both vertically and horizontally, or,

in other words, the oint will be tightened, so as to resist vertical as well as lateral flexure of the joint and to hold the rail ends from movement relatively to each other both laterally and vertically. l

In Fig.- 6 I have shown a modification of the construction illustrated in Fig. 5, embracing a base-pl ate R, like the base-plate G of Fig. 4 or M of Fig. 5, two. joint-bars SS', having outwardly-extending longitudinal upper flanges s and s and lower flanojes s2 s3, two stifiening or girder plates T and which are interlocked with the side margins of baseplate R in the same manner as before described, and track-bolts, one of which is I'n this instance, however, the

upper margins, with inwardly-extending flanges t'and u, having oblique lower faces adapted .to contact with outwardly and downwardly inclined top surfaces s4 35 on the top anges s and s of the j oint-bars S and S', and are also provided near their lower margins and' above the baselate with inwardly-extending horizontal anges t u', having in.- clined or beveled lower faces adapted for contact with downwardly and outwardly inclined surfaces s S7 on the top surfaces of the lower flanges s? s3 on said joint-bars. In this construction the drawing of the girder-plates T and U inwardly in tightening the trackbolts has the effect of forcing the joint-bars downwardly against the base-flanges of the rails in the same manner as before described in connection with Fig. 5, while the presence of the inwardly-extending flanges t t u u on the stiffening-gird ers serve to greatly increase the strength and rigidity thereof.

In the form of joint shown in Fig. 7 the joint has only one girder-plate T, like the` girder-plate T of FigiI 6, and a flanged joint- T and the rails, such as is also shown in said Fig. 6. The ,joint shown in said Fig. 7 has at its side opposite the girder-plate a joint-bar C, like t-he corresponding joint-bar shown in Fig. 3.
